摘要
Introduction. In view of the noteworthy role of adipocytokines in the onset of insulin resistance and diabetes in gene-knockout-rat-model-cell-line studies we aimed to study the influence of genetic predisposition for diabetes on adipocytokine levels and their role in building insulin-resistance-like environment well before the onset of diabetes; thus a hypothesis can be drawn on their role in developing diabetes in high risk population. Methods. Ages between 18 and 22 years were selected and divided into three groups. Group I (n = 81): control group with no family history of diabetes. Group II (n = 157): with one of their parents with history of type 2 diabetes. Group III (n = 47): with both parents having history of type 2 diabetes. In all the groups we estimated fasting plasma glucose, insulin and adipocytokines like adiponectin, leptin, TNF-alpha, and IL-6. Results. Of all adipocytokines we observed significantly lower levels of adiponectin (8.7 + 1 mu g/mL in group III and 9.5 + 1.3 mu g/mL group II) when compared to control (11.0 + 1.2 mu g/mL; P < 0.01) and it has strong correlation with family history of diabetes with Pearson's coefficient of -0.502. Linear regression analysis showed significant negative association with HOMA-IR (P < 0.01) and logistic regression analysis showed highest association with parental diabetes (P < 0.01; OR .260, 95% CI .260-.468). Conclusion. Genetic predisposition for diabetes may influence adiponectin gene expression leading to decrease in its plasma concentration, which might play a key role in developing diabetes in near future.
